DFI SLI Mobos

[Buenamos]

OK, I'm going to be going to college here this next fall and I'm going to upgrade my computer one last time while I still have money from graduation. So basically what I'm thinkin about doin is if Nvidia's G70 is better than ATI's R520 and their "crossfire" setup, I want to atleast have a pretty good plan on what parts to order. For SLI motherboards, I've heard nothing but awesome things about the DFI SLI setups. I've been searching through newegg and I've noticed there are several different ones and I'd like to know if any of you know the actual difference between them.

Theres the:
1) DFI LANPARTY UT nF4 SLI-DR Socket 939 NVIDIA nForce4 SLI ATX AMD (http://www.newegg.com/Product/Product.asp?Item=N82E16813136157)
$174.00

2) DFI LP UT nF4 SLI-D Socket 939 NVIDIA nForce4 SLI ATX AMD (http://www.newegg.com/Product/Product.asp?Item=N82E16813136158)
$178.00

3) DFI LANPARTY nF4 SLI-DR Socket 939 NVIDIA nForce4 SLI ATX AMD (http://www.newegg.com/Product/Product.asp?Item=N82E16813136151)
$196.00

Now, keep in mind that I plan on getting the AMD 3700+ San Diego (http://www.newegg.com/product/product.asp?item=N82E16819103539) and definitely plan on overclocking with my watercooling setup. Also any recommendations on memory? I currently have 2x512mb Geil 4200 ddr but I'd like to get 2x1gb b/c obviously most of u know why i dont want to go 4x512mb.

the DR means that it has an extra raid chip, front x is just frontal connectors and some back ones, like an sata port, check out the dfi site for the entire explication of the different models

just so you know, i believe that they fixed the 4x memory module speed problem with the newer chips with venice, i asume that san diego will have the fix as well

You are partially right. The DR is the extra sata raid chip version versus the SLI-D version. But for the SLI-DR and the UT SLI-DR there is also a difference. The regular non-UT version comes with a front-x panel for the POST indicator lights,front audio,etc. along with a PC transpo which is a carry strap for the pc to go to a actual lanparty. Also comes with UV wire sleeving for your power supply,etc. too. Comes in a huge box too. The UT version of the SLI-DR is without the above, hence the price drop.

number 1 no questions asked .. its a SLI-DR (all features) & cost less then the others.
as for RAM i dont recommend the idea of getting 2GB because its an overkill. stick with you current ones.
